Description

Has the artificial shaft brake of determining the electricity operation of lock and rotation release and automatic resetting characteristics
Technical field
Present invention relates in general to have the machine of running shaft, particularly relate to a kind of shaft brake of improved electricity operation, it have can manually-operated definite lock (positive lock) and rotation discharge and automatically reset feature, be used for this machine.
Background technique
Sometimes need to be provided for the break of axle.
In some cases, wish electric operational brake.Therefore, the break of electric operation is provided.They generally include: housing or body; Coil, this coil are installed on housing or the body; And armature, this armature can selectively move when coil electricity.Elastic member is spring bias voltage armature and away from coil for example.A series of friction pad and brake disks alternately operationally is arranged between armature and the housing, and is arranged to be compressed when coil blackout.One in pad and the dish is connected with running shaft, fill up with coil in another be connected with housing.Therefore, when coil blackout, spring pushing armature, so that the compression friction brake, and make the axle braking.In some cases, need manually make the axle rotation, perhaps need not have live axle under the electric situation.
In some cases, wishing very much has a kind of auxiliary brake, and it can be locked in axle on the housing really.Even such auxiliary brake also will be effectively when axle and housing are subjected to bigger vibration.Also need to make axle to automatically lock, prevent fault or mechanical failure when under the situation that does not have electricity, no longer rotating with the box lunch axle.Therefore, think to be starved of the shaft brake that a kind of electricity is operated that it has manually-operated definite lock, and has rotation to discharge and automatic resetting characteristics.
Summary of the invention
Described embodiment's corresponding part, part or surface, just explanation for example of the reference number in bracket, rather than limit, the present invention provides a kind of improvement to device (20) in a broad sense, and this device (20) has the shaft portion (24) that is mounted for rotation in housing (21).
In a broad sense, improvement comprises: shaft brake (27), this shaft brake is used for selectively engaging, so that preventing axle rotates with respect to housing, and be used for selectively throwing off, so that allow axle with respect to the housing rotation, this break comprises: the axle collar (22), this axle collar is installed on the housing, be used to carry out with respect to the built-up shaft of housing to rotatablely move; First interlocking portions (110), this first interlocking portions is installed on the axle; Annular element (84), this annular element threaded shaft, and be installed on the housing, being used for relative this housing and carrying out axial motion, but do not rotatablely move, these parts have second interlocking portions (85), and this second interlocking portions (85) is arranged to towards first interlocking portions; Spring (124), this spring action and pushes second interlocking portions, so that it is moved towards first interlocking portions between these parts and axle; Wherein, the axle collar is used for respect to housing selectively motion between the primary importance (as shown in Figure 14) and the second place (as shown in Figure 13), in this primary importance, first and second interlocking portions are interlocked with one another, so that preventing axle rotates with respect to housing, and in this second place, first and second interlocking portions are physical separation each other, so that allow axle to rotate with respect to housing.
First and second interlocking portions can be face spline (face spline) parts, and perhaps other type is mechanical interlocked.
The axle collar can be installed on the housing by the spiral connection.The axle collar can be used to be booked and with respect to the housing artificial sport, so that selectively lock and open auxiliary brake.
One of can be used for being connected with spline by key of parts (84) is installed in housing.
Spring (124) can be waved spring, Belleville spring stacking etc.
Device can also comprise the break (37) of electricity operation, is used for selectively operating, so that allow and prevent relatively rotating between axle and housing.Housing can have the mat woven of fine bamboo strips one abutment surface (47) and relative second abutment surface (72).The break of electricity operation can comprise: coil (70), and this coil is installed on the housing; Armature (69), this armature is installed on the housing, is used for towards housing first abutment surface motion and leaves this housing first abutment surface; Elastic member (73), this elastic member acts between housing and the armature, and the pushing armature, so that make it leave housing first abutment surface; Annular wheel hub (77), this annular wheel hub be around first, and be installed on the housing, is used for relatively that this housing carries out axial motion, but do not rotatablely move; And a series of friction pad (74) that replaces and brake disks (75), they are between armature and housing second abutment surface, one in pad and the dish is fixed on the wheel hub, be used for moving with this wheel hub, the pad with the dish in another be connected with housing, like this, when coil electricity, armature will move towards housing first abutment surface, so that allow rotation relatively between axle and housing, and when coil blackout, elastic member will expand, so that make a series of friction pad and brake disks alternately compress between armature and housing second abutment surface.
Axle (24) can comprise first portion (25) and second portion (26).First interlocking portions (110) can be installed in the first portion, and wheel hub (77) can the threaded shaft second portion.
Device also can comprise a plurality of cams (125) and driven device (126), and they act between first and second shaft portions, so that allow to carry out between them some relative rotations.Work as coil blackout, and shaft portion is when moving relative to each other, driven device is along camming movement, is applied to compressive force on a series of friction pad alternately and the dish so that reduce by elastic member (73).This makes friction pad and dish engage again automatically when two shaft portions return their zero relative angular position.In a preferred form, first marginal end portion partly has hexagonal outline, and is used for that the artificially rotates with respect to housing when coil blackout.
Therefore, overall goal of the present invention provides a kind of electromagnetic brake, and this electromagnetic brake has the manual shaft brake interlock.
Another purpose provides a kind of improved shaft brake.
By top and following explanation, accompanying drawing and attached claim, will know these and other objects and advantage.
